Omage Granite Speakers are excellent for the money but a little hard to find. There is a GR306 (6" woofer) and GR 308 (8" woofer), I have both but prefer the 308. You can do a search on ebay and find them for under $160 a pair. They favorably compete with indoor/outdoor speakers at three times the cost.
